What's the “condition” in C interview test?

Question

Would it be possible to print Hello twice using single condition?

if  \"condition\"
  printf (\"Hello\");
else
  printf(\"World\");         


        

Answer 1

The if statement executes one or the other of the controlled statements (both printf in your example). No matter what you use for condition, that snippet will either print "Hello", or "World", but never both.

Edit: Okay, so it's a trick question and you can put whatever you like in the condition (including a call to an entire other function that does anything you want). But that's hardly interesting. I can't believe I got downmodded for giving a correct answer.
